SHINGLE ROOF AND CLIP Filed Feb. 17. 1928 Patented Oct. 8, 1929 UNITED STATES watts GEORGE G. GUERTIN, OF ST. PAUL, MINNESOTA SHINGLE ROOF AND CLIP Application filed February 17,'1928. Serial No; 255,062.

The invention relates to roofs formed of flexible shingles and it is one object of my invention to provide for a new and improved roof construction in which the lower ends of the shingles are stiffened and held againstplished by reference to the accompanying drawing. 5 Fig. 1 is a fragmentarytop plan view.

Figs. 2 and 3 are enlarged sectional views on lines 22 and 3-3 of Fig. 1.

Fig. 4 is perspective view of the clip. Individual shingles are shown on the drawing and are preferably used, but a number of shingles formed integrally, that is, in a strip, could also be used, the same holding means for the lower ends of the shingles being usable in either instance.

The numerals 5 on the drawing, denote a plurality of rectangular starting shingles, that is, shingles used at the lower edge of a roof. Laid upon these shingles, additional shingles 6 have been shown, provided with so pointed lower ends in the present disclosure, although they could obviously be of other shapes. Other shingles 7 of the same construction asthe shingles 6 are laid upon the latter and the roof is completed in the usual way with various rows of overlapping shingles.

At the meeting points of their lower edges, the shingles 5, 6 and 7 are jointly formed with notches 8 (Jo-operable with clips 9 in tightly 40 holding the lower ends of the shingles down, said clips being secured to the lower sides of all shingles but the starters 5, and being centrally disposed at the lower ends of said shingles.

Each clip 9 embodies a metal strip 10 extending from the lower toward the upper end of the shingle and secured to the latter in any desired manner, for instance, by providing said strip with integral upstanding prongs 11 which pass through the shingle and are clinched thereon. The strip 10 effectively stifi'ens the pointed lower end of the shingle and prevents curling even'at the lower extremity. In the construction shown, the lower end of each strip 10 is provided with two downwardly projecting portions 12 which pass through the underlying notch 8, and said strip is also provided with two additional portions 13 projecting laterally with respect thereto and joined to the lower ends of the portions 12. The portions 13 underlie the abutting portions of the shingles through whose notch, the portions 12 extend. Thus, all overlying shingles are effectively anchored at their lower ends to the underlying shingles and hence flapping and curling of said lower ends, are effectively prevented.

In the preferred form of construction, the clip 9 is formed from a single T-shaped metal blank with its shank stamped to provide the prongs 11 and with the end portions of its head bent to provide the portions 1213, above described. This clip construction permits quick and easy manufacture in large number, at exceptionally small expense, the clips may be easily attached to the shingles, and when in use, said clips will be efficient to the maximum for attaining the desired end. Preferably, these clips are attached to the shingles at the factory but this is not abso-eo lutely essential. Whether they be attached at the time of manufacturing the shingles or by the workman applying the roof, they will' 7 entail little additional trouble and expense which willbe counteracted by the increased" efliciency of the roof.

The exact details disclosed are preferably followed. However, within the scope of the invention as claimed, modifications may of course be made. stood that the usual nails (not shown) secure the shingles to the roof.

I claim:

1. A shingle clip comprising an elongated metal strip for attachment longitudinally to 95 the lower side of a shingle, the lower'end of said strip having two elongated tongues projecting laterally from its opposite edges, said tongues each having one right angular bend providing two laterally spaced downwardly too It will of course be under projecting portions for joint passage through an underlying notch, each tongue having a second right angular bend providing other portions projecting laterally of the strip in opposite directions from said downwardly projecting portions to underlie underlying shingle portions.

2. A shingle clip comprising a T-shaped metal blank whose shank is provided with integral longitudinally spaced prongs for attaching it longitudinally upon the lower side of a shingle, the oppositely projecting head portions of said blank being bent first downwardly at right angles and then laterally at right angles in opposite directions.

In testimony whereof I have hereunto affixed my signature.

GEORGE G. GUER'IIN.
